Subject: 24.0.94; Closing Speedbar frame raises error
Date: Tue, 06 Mar 2012 12:00:51 +0100

0. emacs -Q
1. Check "Enter Debugger on Error" in the Options menu.
2. M-x speedbar
3. With the Speedbar frame selected, type `q'.
=>The Speedbar frame vanishes, and in the remaining frame, the following
backtrace appears:

Debugger entered--Lisp error: (error "Attempt to delete the sole visible or iconified frame")
  delete-frame(#<frame Speedbar 1.0 0x89f3f80>)
  window--delete(#<window 8 on  SPEEDBAR> t t)
  replace-buffer-in-windows(#<buffer  SPEEDBAR>)
  kill-buffer(#<buffer  SPEEDBAR>)
  dframe-close-frame()
  call-interactively(dframe-close-frame nil nil)

No error is raised if steps 0-2 are repeated and at step 3 `Q'
(delete-frame) is typed.

Note that the frame consists of a single window containing the
*Backtrace* buffer (normally, a backtrace splits the window).  Moreover,
typing `q' (top-level) in this buffer deletes the backtrace, but an
empty *Backtrace* buffer remains as the current buffer (normally, `q'
kills the *Backtrace* buffer.)
